PCBA Details:

Circuit composition

It mainly contains the main control chip, which is the "brain" of the PCBA, which is responsible for processing and coordinating all the signals. For example, it can receive touch location information from an infrared touch sensor.
There are multiple driver circuits corresponding to the infrared emitter and the receiver tube, which can precisely control the infrared emitted by the transmitter tube and make the receiver tube effectively receive the signal.
At the same time, there is also a power supply circuit, which is used to convert and regulate the external input power supply, ensuring that each chip and component can operate at a stable voltage, such as converting 220V AC to 5V, 3.3V and other DC voltages.

Component layout details

The component layout is usually divided by functional modules, and the elements of the infrared touch sensing part are concentrated close to the edge of the touch screen, so that the infrared signal from the screen surface can be better received and processed.
Core components such as the main control chip will be placed in an area with better heat dissipation, and a certain amount of space will be reserved around it to avoid signal interference. At the same time, there will be a lot of filter capacitors distributed around the chip to filter out clutter in the power supply.

Interface details

It has a USB port for data transfer with external devices (such as computers), such as transmitting touch signals to computers for further processing.
There is also the power connector, which has clearly defined pins to ensure proper power access. Some will also have a video output interface for easy connection to other display devices for signal synchronization.

PCB Application scenarios:

Educational applications

It is widely used in intelligent teaching equipment in school classrooms, and teachers can display teaching courseware on the screen through touch operation, annotate and explain, and facilitate students' understanding.
It can also be used on the electronic whiteboard of education and training institutions to achieve interactive teaching, such as students can answer questions and draw on the screen.

Commercial display use

In the advertising machine in the mall, consumers can touch the screen to obtain product information, view the details of promotions, or experience virtual goods.
The display equipment used in the enterprise exhibition hall can display the company's products, development history, technical advantages and other contents through touch interaction to enhance the display effect.

Conference system scenario

In the smart conference tablet in the conference room, participants can use touch to share files, mark documents, brainstorm, etc., to improve meeting efficiency.
For remote meetings, the video conferencing software can be controlled by touch operation, which is convenient for communication and collaboration between people in the two places.

Features:

Touch performance aspect

With high sensitivity, it can accurately detect touch movements, even the slightest touch can be quickly responded, and the minimum touch object diameter can reach a few millimeters.
The touch accuracy is high, the touch positioning error is small, and it can be accurate to the pixel level, ensuring that the user's operation is accurate.

Stability features

Strong working stability, in the process of long-term use, there will be no performance degradation or failure due to heating and other problems, and it can work continuously and stably.
Excellent anti-interference ability, in complex electromagnetic environments, such as when there are many other electronic devices around, it can still work normally, and there will be no false triggering.

Fit characteristics

It can be adapted to a variety of operating systems, including Windows, Android, Linux, etc., so that different users can choose according to their needs.
It also has good adaptability to different software applications, whether it is office software, teaching software or display software, it can be well matched to achieve touch operation.
